Hong Kong Observatory forecasts confirm a high of 28–30°C on March 26 under a dominant high-pressure ridge delivering warm, dry continental air, solidifying trader consensus at 100% implied probability for 28°C or higher. Ensemble models from global systems like ECMWF and GFS show tight agreement on peak afternoon temperatures well above the March climatological average of 23°C, fueled by clear skies and light winds enhancing solar heating. Recent observations through March 25 logged similar highs, with no frontal systems in steering patterns to disrupt. An abrupt cool air advection—unlikely given synoptic setup—remains the sole realistic challenger, pending final hourly updates from the Observatory.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm
This market can not resolve to "Yes" until data for this date has been finalized.
The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
